Bush Immigration Plan Meets GOP Opposition, The Washington Post
Excerpts: The key prong in Bush's plan is a temporary-worker program that would offer the nation's estimated 10 million illegal immigrants a chance to earn legal status that would allow them to stay in the country as long as six years. Once they register as temporary workers, they would be eligible to begin the long process of applying for citizenship or permanent residency.

In Plan to Reduce Deficit, White House Turns to Old Projections, NY Times
Excerpts: To show that President Bush can fulfill his campaign promise to cut the deficit in half by 2009, White House officials are preparing a budget that will assume a significant jump in revenues (...).
To make Mr. Bush's goal easier to reach, administration officials have decided to measure their progress against a $521 billion deficit they predicted last February rather than last year's actual shortfall of $413 billion.
By starting with the outdated projection, Mr. Bush can say he has already reduced the shortfall by about $100 billion (...).
Editor's Note: Arguments based on predictions instead of facts seem to be a popular method to fabricate desired interpretations of reality. This seems to work from optical illusions and magic tricks, to "creative accounting" in the style of Enron all the way to government fiscal policies.

Excerpts: Administration officials say that these and other measures would stimulate savings, which are crucial to increasing long-term growth. (...).
But other analysts are skeptical. (...) personal savings plunged during the last four years even though tax subsidies for retirement accounts increased modestly over the same period. The reason, he theorized, is that many people do not use tax-advantaged accounts to save more money. Instead, they simply move their existing savings into new tax-advantaged accounts when the opportunity arises.
Reacting to a Dollar With No Muscle, NY Times
Excerpts: The currency movements also mean that for American investors overseas markets generally did better than American ones. While leading European markets were up less than 10 percent in euro terms, because of the euro's appreciation they showed double-digit gains when measured in dollars.
Even so, American investors were less interested in European stocks in the past year than in Chinese ones - or at least in companies that could claim to benefit from the Chinese boom. (...) there is little indication that the urge to buy Chinese will stop.
We Have Met The Other And We're All Nonlinear: Ethnography As A Nonlinear Dynamic System, Complexity
Excerpt: Just as complexity changes notions of what "science" is, ethnography offers an alternative model for "social science." Particularly striking for ethnography is the family resemblance between its social research tradition and complex adaptive systems. In fact, if ethnography is seen as a CAS, several key issues appear in a new light. In this article, ethnographic research is looked at in terms of its algorithmic complexity, its sensitivity to initial conditions, the presence of an ethnographic agent, the fractal structure of method and results, and the problem of representation.

Devastating Quake Redraws Map, Nature News
Sunday's destruction was unleashed by a 'megathrust' - a huge, sudden juddering movement beneath the ocean floor. Here, a buildup of pressure caused the Indian Ocean floor to lurch some 15 metres towards Indonesia, burrowing under its tectonic plate and triggering the ferocious swells that smashed the surrounding shores.
This image shows how the wave moved towards the surrounding coasts. Click here
to see the animation. ? Animation provided by Kenji Satake, National Institute of Advanced Industrial Science and Technology, Japan?
The movement is likely to have altered the geography of neighbouring islands such as Simeulue, the Nicobar and Andaman islands, and Sumatra itself, says Bill McGuire, a geophysicist at University College London, UK.
"The tsunami propagation is also animated (up to 5 hours) from a 1200 km fault. The red color means that the water surface is higher than normal, while the blue means lower. It indicates that initial tsunami to the east (e.g., Phuket) began with receding wave, while to the west (e.g., Sri Lanka) large wave suddenly reached. The darker the color, the larger the amplitude.? The tsunamis were larger in the east and west directions. "
Excerpts: The great earthquake (Mw 9.0) of December 26 off Sumatra generated the tsunami in the Indian Ocean. According to U.S.G.S., the aftershocks extended as far as 1,000 km toward north (the red circles indicate aftershocks occurred within 24 hours). Assuming that the aftershock area represents the tsunami source, the tsunami propagation was computed.
The Future of Calamity, NY Times
Excerpts: In seven hours last week, great ocean waves scoured shores from Thailand to Somalia, exacting a terrible price in wealth and human lives.

Feeding Behaviour: Hydrothermal Vent Crabs Feast On Sea 'Snow', Nature
Abstract: The crab Xenograpsus testudinatus lives at enormously high densities around the sulphur-rich hydrothermal vents found in shallow waters off Taiwan, even though this acidic environment is low in nutrients. Here we show that these crabs swarm out of their crevices at slack water and feed on the vast numbers of zooplankton that are killed by the vents' sulphurous plumes, and that rain down like marine 'snow'. This opportunistic feeding behaviour explains how the crabs are able to survive in the adverse toxic environment of these shallow hydrothermal vents.

Novel Calendar System Creates Regular Dates, New Scientist
Excerpts: A US physicist is lobbying for people to adopt his novel calendar in which every date falls on the same day of the week each year. The current calendar, which runs for 365 days, was instituted by Pope Gregory in 1582 to bring the length of the year in line with the seasons. But because the Earth actually orbits the Sun every 365.24 days, a 366-day "leap year" must be added every four years to account for the extra fraction of a day. In this Gregorian system, a given date (such as New Year's Day) falls on different days of the week in different years because 365 is not evenly divisible by seven.

Reinventing the Wheel (and the Tire, Too), NY Times
The first automobile to use air-filled tires was a racecar built by André and Édouard Michelin in the early 1890's. (...)
The Tweel, an experimental tire and wheel combination developed by Michelin, is designed to replace today's air-filled tires. Flexible polyurethane spokes deflect over obstacles.
Now, after decades spent persuading the world to ride on air, the company has begun work on an innovation that could render the pneumatic tire obsolete. Engineers at Michelin's American technology center here envision a future in which vehicles would ride on what they call the Tweel, a combined tire and wheel that could never go flat because it contains no air.

Robustness, Evolvability, and Neutrality, SFI Working Papers
Abstract: Biological systems, from macromolecules to whole organisms, are robust if they continue to function, survive, or reproduce when faced with mutations, environmental change, and internal noise. I focus here on biological systems that are robust to mutations and ask whether such systems are more or less evolvable, in the sense that they can acquire novel properties. The more robust a system is, the more mutations in it are neutral, that is, without phenotypic effect. I argue here that such neutral change - and thus robustness - can be a key to future evolutionary innovation, if one accepts that neutrality is not an essential feature of a mutation. That is, a once neutral mutation may cause phenotypic effects in a changed environment or genetic background. I argue that most, if not all, neutral mutations are of this sort, and that the essentialist notion of neutrality should be abandoned. This perspective reconciles two opposing views on the forces dominating organismal evolution, natural selection and random drift: Neutral mutations occur and are especially abundant in robust systems, but they do not remain neutral indefinitely, and eventually become visible to natural selection, where some of them lead to evolutionary innovations.

First 'Atlas' Of Key Brain Genes Could Speed Research On Cancer, Neurological Diseases, Innovations Report
Excerpts: Scientists link gene 'switches' to specific brain locations Researchers at Dana-Farber Cancer Institute have compiled the first atlas showing the locations of crucial gene regulators, or switches that determine how different parts of the brain develop - and, in some cases, develop abnormally or malfunction. The scientists say the map will accelerate research on brain tumors and neurological diseases that result from mutations in these switch genes - called "transcription factors." When these genes are altered, the genes they control can go awry, causing abnormalities in the development or function of nerves and related structures.
Excerpt: Granted that truth is valuable we must recognize that certifiable truth is hard to come by, for example in the natural and social sciences. This paper examines the case of mathematics. As a result of the work of Gödel and Tarski we know that truth does not equate with proof. This has been used by Lucas and Penrose to argue that human minds can do things which digital computers can't, viz to know the truth of unprovable arithmetical statements. The argument is given a simple formulation in the context of sorites (Robinson) arithmetic, avoiding the complexities of formulating the Gödel sentence. (...)

Turning Memory Development Inside Out, Dev. Rev.
Excerpt: These papers provide a useful progress report on how the mature and successful field of memory development is transcending traditional boundaries of populations, content, context, and design. Examining children's memory for distant as well as recent occurrences, for social interactions as well as individual experiences, for meaningful as well as arbitrary information, and for emotion-laden as well as neutral experiences is creating a broader and more vigorous field. Even greater progress can be made by measuring at a fine grain level the processing activities that experiences elicit, how such immediate processing activities shape later memory (...).

Magnesium May Reverse Middle-age Memory Loss, ScienceDaily
Excerpt: Magnesium helps build bones, make proteins, release energy stored in muscles and regulate body temperature. (...) researchers report a possible new role for magnesium: helping maintain memory function in middle age and beyond. The adult daily nutritional requirement for magnesium, a trace mineral found in foods such as dark green, leafy vegetables, is around 400 mg a day. But studies show that as many as half of all Americans do not consume enough magnesium. Magnesium deficits have been tied to allergies, asthma, attention deficit disorder, anxiety, heart disease, muscle cramps and other conditions.

The monks who had spent the most years meditating had the highest levels of gamma waves, he added.
Temperature-Dependent Sex Ratio In A Bird, Biol. Lett.
Excerpt: To our knowledge, there is, so far, no evidence that incubation temperature can affect sex ratios in birds, although this is common in reptiles. Here, we show that incubation temperature does affect sex ratios in megapodes, which are exceptional among birds because they use environmental heat sources for incubation. In the Australian brush-turkey Alectura lathami, a mound-building megapode, more males hatch at low incubation temperatures and more females hatch at high temperatures, whereas the proportion is 1:1 at the average temperature found in natural mounds. Chicks from lower temperatures weigh less, which probably affects offspring survival, but are not smaller. (...)

The Song of the Dunes as a Self-synchronized Instrument, arXiv
Abstract: Since Marco Polo it has been known that some sand dunes have the peculiar ability of emitting a loud sound with a well defined frequency, sometimes for several minutes. The origin of this sustained sound has remained mysterious, partly because of its rarity in nature. It has been recognized that the sound is not due to the air flow around the dunes but to the motion of an avalanche, and not to an acoustic excitation of the grains but to their relative motion. By comparing several singing dunes and two controlled experiments, one in the laboratory and one in the field, we here demonstrate that the frequency of the sound is the frequency of the relative motion of the sand grains. The sound is produced because some moving grains synchronize their motions. The existence of a velocity threshold in both experiments further shows that this synchronization comes from an acoustic resonance within the flowing layer: if the layer is large enough it creates a resonance cavity in which grains self-synchronize.

Abstract: Diffusion rates through a membrane can be asymmetric, if the diffusing particles are spatially extended and the pores in the membrane have asymmetric structure. This phenomenon is demonstrated here via (i) deterministic simulations of a two-species hard-disk gas, (ii) simulations of two species in Brownian motion, diffusing through a membrane which is more permeable to one species than the other, and (iii) simulation of diffusion in a simple network model. In its extreme form, this effect will rapidly seal off flow in one direction through a membrane, while allowing free flow in the other direction. A single species of appropriately shaped particles will exhibit the same effect when diffusing through appropriately shaped pores. We hypothesize that purely geometric effects discussed here may play a role in common biological contexts such as the potassium ion channel.
There are a handful of mathematical models of snowflake growth, says Reiter, but most involve fiendishly complicated differential equations.
Computer snowflakes are surprisingly easy to make.
So Reiter tried to make snowflakes using mathematical processes called cellular automata. These are sets of simple rules that can generate extremely complex forms when applied to a system over and over again. Unlike a differential equation, which tries to describe the whole snowflake, a cellular automaton just looks at a tiny part of the whole structure, and describes it in relation to areas that have already been built.
Editor's Note: Lattice-gas automata for the Navier-Stokes equation had been developed by Frisch, Hasslacher, Pomeau, Wolfram and others already almost twenty years ago and had proven to be very useful for many applications.
But anyway, we haven't seen decorative CA movies for a while, and the Christmas spirit probably influenced the nature editors in their publication decision.
Alcoholism And Excessive Food Intake May Share Chemical Pathways In The Brain, ScienceDaily
Excerpts: Galanin is one of several neuropeptides known to increase food intake. Previous findings have suggested that galanin may also be involved in alcohol consumption and/or the motivation to drink alcohol beverages. Most recently, researchers have discovered that giving galanin microinjections to rodents can increase their voluntary alcohol intake. (...) "Galanin's well-known effects of increasing food intake, especially the intake of fat-rich diets, was one of the early reasons we investigated it, (...). Alcohol is the only drug of abuse that can also qualify as a calorie-rich food, and it undoubtedly has important interactions with systems that control food intake and nutrition." (...)
Can Game(s) Theory Explain Culture? The Emergence of Cultural Behavior within Multiple Games, SFI Working Papers
Abstract: The hallmarks of "cultural behavior" are consistency within and across individuals, variance between populations, behavioral stickiness, and suboptimal performance. In this paper, we build a formal framework within which we can derive each of these five behavioral attributes. Our framework rests on two primary assumptions: (i) agents play ensembles of games, not just single games as is traditionally the case in evolutionary game theory models and (ii) agents have finite cognitive capacity. Our analysis combines agent-based techniques and mathematics. The former enable us to explore dynamics and the latter allow us to prove when the behaviors produced by the agents are equilibria. Our results provide game theoretic foundations for cultural diversity and agent-based support for how cultural behavior might emerge.
Middle and Long Distance Athletics Races Viewed from the Perspective of Complexity, Journal of Theoretical Biology
Abstract: Middle and long distance athletics races behave as power-laws when time (or average speed) and distance are related, thus suggesting the presence of critical phenomena. Power-laws as a function of the athlete's position in the all-time world ranking allows us to define a Performance Index that reveals the existence of possible multifractal structures associated to the natural barriers to that the athletes tend in their evolution towards better results and in pursuit of world records. The new theories of self-organized critical phenomena provide an explanation for the power-law and fractal structures in systems at, or near, their critical points. In this paper we analyse the athletic races using these theories and as a result of this study a new variety of interpretations are posited.
The Partisan Paradox Religious Commitment And The Gender Gap In Party Identification, Public Opin. Quart.
Excerpt: A large body of scholarly literature points to the growing influence of religious devotion on U.S. partisanship. This article attempts to reconcile the growing religious commitment cleavage in the American party system with the commensurate growth in the gender gap. If women are, on average, more religiously devout than men, and if contemporary shifts in partisanship are disproportionately founded on religious and cultural cleavages, then why are women more likely to identify with the Democratic Party? I pose three possible explanations for this apparent paradox: (...).
Experiences Make People Happier Than Material Goods, ScienceDaily
Excerpts: When it comes to spending money in the pursuit of happiness, the "good life" may be better lived by doing things rather than by having things, according to a University of Colorado at Boulder researcher. In a society that thrives on the pursuit of happiness, a question that often comes to mind, especially around the holiday shopping season, is what really makes us happy. (...) Through a series of surveys and experiments spanning several years, Van Boven found that people from various walks of life were made happier by investing their discretionary income in life experiences than in material goods.
